Anti-AIDS Agents. 48. Anti-HIV Activity of Moronic Acid Derivatives and the New Melliferone-Related Triterpenoid Isolated from Brazilian Propolis

Abstract
A new triterpenoid named melliferone (1), three known triterpenoids, moronic acid (2), anwuweizonic acid (3), and betulonic acid (4), and four known aromatic compounds (5−8) were isolated from Brazilian propolis and tested for anti-HIV activity in H9 lymphocytes. Moronic acid (2) showed significant anti-HIV activity (EC50 186) and was modified to develop more potent anti-AIDS agents.
